In the making of meat products exemplified by frankfurters, skinless wieners, boneless ham, cottage butt, Canadian bacon, leona sausage, salami, the appropriate meat containing water is enclosed in a semi-permeable membrane, and the enclosed meat is cooked by immersion in a heating liquid, e.g. a liquid of 5 parts of water, 4 parts of glucose and 1 part of sodium chloride, which withdraws water from the meat through the membrane. The cooking liquid is preferably maintained at 160-190‹F., and the meat product is immersed therein until the internal temperature of the meat is at least 138‹F., e.g. for 12 mins. After cooking, the products may then be sprayed with cold water and pased through a tank of iced water for about 7 mins. The semi-permeable membrane is preferably stripped off at this stage, whilst still wet.

Title: Improvements in or relating to photo-electric indicator circuits
Inventor: WILSON JOHN
IPC: H03K17/94
Filed: 1961-12-27
Abstract: 949,651. Photo-electric detector circuits. PYRENE CO. Ltd. Dec. 18,1962 [Dec.27, 1961], No. 46275/61. Heading G1A. [Also in Divisions G4 and H3] A photo-electric detector circuit comprises a photo-electric device 4, a lamp 1 which will cause illumination of the device 4 when a condition such as the presence of smoke in a tube prevails, means for providing a test illumination of the device 4, indicator means 24 operated by the device 4 when it is illuminated and means for re-setting the indicator means to an unoperated condition, and means for maintaining the indicator means in an operated condition once the photo-electric device has been illuminated, in combination with means responsive to the operation of the indicator means to suppress simultaneously the illumination of the photo-electric device. In the embodiment shown the invention is used in a smoke detector system of the kind where a lamp 1 and a photocell 4 are arranged on opposite sides of a chamber (not shown) with a mask 5 between them so that the photo-cell is only illuminated when smoke is present in the tube, by light diffused by the smoke and a further lamp 6 is provided to enable the photo-cell to be illuminated directly, for test purposes. When the photo-cell 4 is illuminated its drop in resistance causes the output signal from an amplifier 8 formed by transistors 9, 10, 16, 21 to energize a relay RL/2 which closes a contact RL1 to light an indicator lamp 24 and opens a contact RL2 thus disconnecting both lamps 1 and 6 from a supply line 3. Opening of the contact RL2 introduces a resistor 26 into the potential divider formed by a resistor 25 and the photo-cell 4 with the effect that the base of the transistor 9 is kept sufficiently negative with respect to its emitter to hold the amplifier in the condition where the relay RL/2 is kept energized. The indicator lamp 24 can then only be switched off by moving a switch SW1 to a RESET position whereby the base of the transistor 16 is earthed causing the relay RL/2 to be de-energized. If the filament of the lamp 1 is broken then the indicator lamp 24 is extinguished immediately on release of the test switch SW1 from the TEST position because without the filament in parallel with resistor 25 and the photo-cell 4 the input voltage to the amplifier 8 is insufficiently negative to keep the relay energized. A temperature sensitive element 13 is included in the amplifier circuit 8 to stabilize the operation of the arrangement against variations of output across a load resistor 15 with temperature changes. The test lamp 6 may be replaced by a solenoid operating a reflector flap which reflects light from the primary lamp 1 on to the photo-cell 4.

Abstract: A lubricating oil additive comprises an arcenic dialkyl dithiophosphate in which the alkyl groups are C1 to C20 straight-chain alkyl groups and/or C1 to C30 branched-chain alkyl groups (see Division C2).ALSO:Arsenic dialkyl dithiophosphates are obtained by reacting an arsenic trihalide, preferably the chloride, and a metal salt of a dialkyl dithiophosphoric acid, or a mixture of the salts of two or more different dialkyl dithiophosphoric acids. The alkyl group is preferably a C1 to C20 straight-chain alkyl group or a C1 to C30 branched-chain alkyl group.  The reaction may be carried out by dissolving each reactant in an organic solvent, e.g. ethanol, and mixing the solutions of reactants.  A example is given for the preparation of arsenic di-(4-methylpentyl-2) dithiophosphate. The products may be used as lubricating oil additives.  The metal salt of the dithiophosphate may be prepared by mixing an alcoholic solution of a metal hydroxide, e.g. KOH, with an alcoholic solution of the dithiophosphoric acid.

Abstract: 1,177,147. Machine tool details. FORD MACHINERY CO. 26 Oct., 1967 [2 Nov., 1966], No. 48793/67. Heading B3B. [Also in Division G3] An apparatus for positioning a driven member of a machine tool includes an hydraulic motor, driving the member, controlled through a servo-electric valve, the opening of which is adjusted to programmed values in dependence on the registration of predetermined numbers of electrical impulses representative of increments of movement of the member. As shown, a workpiece W is fed by interconnected rolls 10 driven through gearing 12, 13 by an hydraulic motor controlled through an electro-hydraulic valve. The position of the valve is determined by the sum of the inputs to an integrator 29. Incremental movement of the workpiece W is sensed by a proximity pick-up, responsive to a toothed wheel 17, triggering a pulse-generator, the output of which is shaped differentiated and rectified and applied to count-up a length counter. The length counter forms an element of a pulse counter which is manually preset to generate a number of outputs each one occurring after receipt of its particular predetermined number of pulses. These pulse numbers are programmed in dependence on the distance that the workpiece has to move to reach its final position. Initially, the intermediate step is turned on and then, after a distance determined by an acceleration counter, a high speed step. Subsequently the high speed step is turned off at the set count and then the intermediate step and slow-speed step. Final positioning is initiated by a manually set reference synchro, the angular position of which is compared with an actual position synchro 19 by a synchro demodulator providing a signal reducing to zero at the programmed final position. The constant level signals from the steps and the variable level demodulated position error signal are summated by the integrator 29 and determine the opening of the electrohydraulic valve. A timer counter is programmed to emit a number of output signals and is initiated by a position completion signal from the length counter on a line 33. Firstly, a brake is applied to the motor shaft, then a clutch 16 is disengaged by a clutch control relay and the position synchro 19 rotated by a reset motor 20 until a detent 37 engages an abutment of a snail cam 18. Down-stream equipment, such as a shear or press is then subsequently initiated through a line 38 by the timer counter. The final signal in a cycle of the timer counter initiates through a line 27, the reset positioning operation after a recycle delay over lines 42.

A magnetic coupling comprises a driving member 2 having inserts of magnetizable material 2a, 2b in a non-magnetic plate, a coupling element which comprises a plurality of stationary polepieces 3, 4, 5, 6 of magnetic material and a driven member 7 which has areas 8 of magnetic material alternating with areas 9 of non-magnetic material (holes in a plate as described), the pitch of such areas being less than the pitch of polepieces 3, 4, 5, 6. A magnetic field across the coupling is produced by poles 1. In operation, member 2 rotates and as the magnetic flux is directed through each polepiece 3-6 in turn, a unidirectional torque is applied to driven member 7 which rotates at 3/11 the speed of the driving member. The coupling may be modified by altering the number of coupling elements to obtain different speed ratios. If a coupling having two coaxial sets of magnetizable parts in each element is used together with selective energization of electromagnets associated with the coupling elements various speed ratios can be obtained, Fig. 7 (not shown). A number of units can be arranged in cascade with the driven number of the first unit integral with the driving member of the second unit and so on, Fig. 6 (not shown).
